Encoding 3Q0/3QD* (MFK 2.0) camera assistants¶
This manual is only suitable for cameras 3Q0980654
Lane Assist with adaptive lane guidance — adaptive guidance eliminates “ping-pong” from lane to lane.
The option is excellent: it lets you relax behind the wheel without hunting for the center of the lane; on the highway it is simply indispensable.
Traffic Jam Assist — traffic jam assistant.
This extends Lane Assist to work from 0 km/h. In a traffic jam the car steers, accelerates and brakes on its own. After stopping for more than 3 seconds, press RES or the accelerator to move off.
Emergency Assist — emergency stop assistant.
If the driver will not or cannot take part in driving, the car first wakes them with sound, then with sharp braking.
If they still do not take control, the car switches on the hazard lights and stops.
Sign Assist — traffic sign recognition assistant. Shows signs read by the camera.
